Abstract
An energy storage cell, in particular a lithium-ion cell, comprising an in particular cylindrical housing main body which extends along a longitudinal axis and forms an arrangement space in which electrode material that is electrically conductively connected to the housing main body is arranged. The arrangement space is delimited at a second end by a cover element and at a first end by a base element. The base element is fastened electrically conductively and gas-tightly to the housing main body by electromagnetic pulse welding.

An energy storage cell comprising:
- a housing body which extends along a longitudinal axis and forms an arrangement space in which electrode material is arranged and has been connected to the housing body in a electrically conducting manner,
- wherein the arrangement space is delimited at a second end by a cover element, and at a first end by a base element, and
- wherein the base element has been fastened to the housing body in electrically conducting and gastight manner by electromagnetic pulse welding.
A method for producing an energy storage cell, comprising:
- making available a housing body which extends along a longitudinal axis and has been designed to form an arrangement space for electrode material;
- arranging electrode material in the arrangement space, and establishing an electrically conducting connection to the housing body;
- and,
- fastening a base element to one end of the housing body by electromagnetic pulse welding for the purpose of establishing a gastight connection.
